RE: License unknown

hi alasdair,



i think a dataset could be offered under more than one kind of license.



i do know that, for some software products anyway, neo4j, have more than
one type of license.  i can see a company like ingenuity, with its curated
data, having a similar business model for their commercial curated
datasets, one for researchers and one for pharma perhaps.



cheers,

michael

Hi Jerven,



We are trying to ensure that a license is provided for a dataset, and that
only one license is provided. (We are closing the world in certain areas.)



Our proposed solution is written up at

Hi Alasdair,

It is good practice in my opinion to not state unknown facts. If you
want to state there should be a license but you don't know it I think
some owl modelling is called for.

e.g. roughly like this.

dusty_data a dct:Dataset .
dusty_data rdfs:subClassOf [ a owl:Restriction ;
                                           owl:onProperty dct:license ;
                                           owl:minCardinality 1 ]


If anyone does something like

dusty_data a dct:dataset .
dusty_data dct:license bad_example:unknown_license .

and then someone figures out it has a license .

dusty_data a dct:Dataset .
dusty_data dct:license cc:zero .

And puts all those triples into one store/ontology then queries will
start to return wrong data.

SELECT ?datasetWithALicense
WHERE {
?datasetWithALicense dct:license ?license .
}

Will give 2 bindings for ?dataset and ?license one of them being wrong now.

If you ask the same question depending on the better modelling then
you get the correct answer in both cases.

SELECT ?datasetWIthoutLicense
WHERE {
?datasetWIthoutLicense a dct;Dataset .
MINUS ( ?datasetWIthoutLicense dct:license ?license )
}

SELECT ?datasetWIthALicense
WHERE {
?datasetWIthALicense a dct;Dataset .
?datasetWIthALicense dct:license ?license .
}

Both give the expected results.


In general in RDF just state what you know and describe what you don't know.

Regards,
Jerven

Hi,

I am working to help shape the Healthcare and Life Sciences community
profile for describing datasets, current version available from [1]

One of our goals is that there is a minimal set of properties that are
available for all datasets, and we would like these properties to include
the license. However we have the problem that for several legacy datasets
the license is simply unknown. Does anyone know of a resource that can be
used to represent that the license is unknown as the value of a
dcterms:license predicate?

Thanks

Alasdair
